Thank you for the feedback!

I am happy to let you know that we have introduced the concept of 'impressions per day in the new message manager experience as a way to track message performance over time.

For a live campaign, these are the impressions for this period divided by the number of days in the period. For all time, it is impressions divided by the number of days it has been live.

We also introduced the concept of the best-performing message over time. Your best-performing messages will be listed here, displaying their impressions per day for the past 60 and 30 days, as well as the percentage change in performance. So if you’ve made an edit to a message and the number of impressions has increased, you can report on the impact your update has had.

Here is the product update for the new message manager experience - https://app.triptease.io/updates/new-message-manager
